so you are doing it the same way, via the fstab config file?

it seems like the device is mounted right until after the vserver is up.

I included a "ls -la /vservers/test01/ ; df -a" in the prepre-start script and it actually outputs a
listing of the guest system. This might be from a different ctx (i.e. 1)???
Because after the guest system is started, and I return to the normal hostsystem shell, a "ls -la
/vservers/test01" outputs an empty directory.
